7.5" Oval Single Ply Chimney Liner Kit

The 7.5 Inch Oval Single Ply Chimney Liner Kit is a durable stainless steel chimney liner designed for installations where a standard round liner will not fit. Made from premium 316 stainless steel, this liner kit is ideal for relining masonry chimneys while protecting against corrosion, moisture, and flue gas leaks.

This 7.5 inch oval chimney liner kit is commonly used for larger appliances in tight or rectangular flue spaces where proper sizing is critical for safe venting. It is especially useful when a 7" or 8" round liner will not fit but proper airflow must still be maintained. Its single-ply flexible construction allows for easier installation while still maintaining strength and durability for long-term performance.

If a properly sized round chimney liner cannot fit inside your flue, an oval liner provides a safe and effective alternative without sacrificing venting performance.

Key Features: 7.5" oval sizing (outside dimensions vary), single-ply flexible construction, .006" wall thickness, 316 stainless steel, UL 1777 listed, made in the USA, lightweight design, and lifetime warranty.
